When Do Jumps Matter for Portfolio Optimization?
(2015-11-25)
We consider the continuous-time portfolio optimization problem of an investor with constant relative risk aversion who maximizes expected utility of terminal wealth. The risky asset follows a jump-diffusion model with a ...
The Dynamics of Crises and the Equity Premium
(2015-05-18)
It is a major challenge for asset pricing models to generate a high equity premium and a low risk-free rate while imposing realistic consumption dynamics. To address this issue, our paper proposes a novel pricing channel: ...
Stochastic Differential Utility as the Continuous-Time Limit of Recursive Utility
(2013-05-10)
We establish a convergence theorem that shows that discrete-time recursive utility, as developed by Kreps and Porteus (1978), converges to stochastic differential utility, as introduced by Duffie and Epstein (1992), in the ...
Partial Information about Contagion Risk, Self-Exciting Processes and Portfolio Optimization
(2013-04-18)
This paper compares two classes of models that allow for additional channels of correlation between asset returns: regime switching models with jumps and models with contagious jumps. Both classes of models involve a hidden ...
Asset Prices in General Equilibrium with Recursive Utility and Illiquidity Induced by Transactions Costs
(2015-02-01)
In this paper, we study the effect of proportional transaction costs on consumption-portfolio decisions and asset prices in a dynamic general equilibrium economy with a financial market that has a single-period bond and ...
Measuring Ambiguity Aversion: A Systematic Experimental Approach
(2014-06-20)
This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ...
Investment-Specific Shocks, Business Cycles, and Asset Prices
(2016-03-14)
We introduce long-run investment productivity risk in a two-sector production economy to explain the joint behavior of macroeconomic quantities and asset prices. Long-run productivity risk in both sectors, for which we ...
Optimal Consumption and Portfolio Choice with Loss Aversion
(2016-05-16)
This paper analyses the consumption-investment problem of a loss averse investor equipped with s-shaped utility over consumption relative to a time-varying reference level. Optimal consumption exceeds the reference level ...
Heterogeneity in the Internationalization of R&D: Implications for Anomalies in Finance and Macroeconomics
(2017-10-17)
Empirical evidence suggests that investments in research and development (R&D) by older and larger firms are more spread out internationally than R&D investments by younger and smaller firms. In this paper, I explore the ...
Volatility-of-Volatility Risk
(2018-05-01)
We show that time-varying volatility of volatility is a significant risk factor which affects the cross-section and the time-series of index and VIX option returns, beyond volatility risk itself. Volatility and ...
